Abstract
In accordance with an embodiment of the present invention, a comparator system includes a plurality of multiplexers adapted to multiplex a number of differential input signals and a number of differential reference signals. A differencing circuit receives a differential input signal and a differential reference signal from the multiplexers and provides a differential output signal, which is used to provide a differential comparator output signal. A latch may be provided to perform differential-to-single ended conversion on the differential comparator output signal to provide a latch output signal. An output circuit may provide a registered digital output signal based on the latch output signal.
